Vultures Slow the spread of Rabies
The world vulture population is shrinking because of modern ranching and farming techniques.
The advent of 20th century farming replaced wild herd animals, whose carcasses are the staple diet of vultures around the world, with heavily medicated livestock. Diclofenac, a frequently administered anti-inflammatory veterinary painkiller comparable to ibuprofen, has proven to be particularly deadly to the vultures that ingest it secondhand. Though the birds by design have "very strong stomach fluids" that digest even the nastiest of pathogens, this particular drug has proven too much, says Tom Aversa of Seattle's Woodland Park Zoo.
But the decline in vultures has meant a rise in rabies!
Countries where vultures are most threatened, such as Nepal, India and Pakistan, rely heavily on vultures for a kind of natural maid service: as they clear out dead animals, the risk of disease is also reduced. Dangerous wild-dog packs that feed on dead livestock have also flourished without competition from the birds, says Todd Katzner of Pittsburgh's National Aviary, leading to a new surge of rabies, particularly in Mumbai. "People don't realize what a key role vultures play in the ecosystem," says Aversa. "[They] prevent disease and recycle."
So the answer: Vulture Awareness!
On Sept. 5 — the first annual International Vulture Awareness Day — zoos and bird societies around the globe will sponsor educational tours and flight demonstrations to get the word out about the plight of the vultures. Unlike blue whales, polar bears and other beloved species in danger of extinction, it may be harder to rally folks to save these prickly feathered birds with bumpy, bald heads, portly physiques and a tendency to be knee-deep in rotting flesh.
Better the rotting rabid flesh be in the belly of a vulture, I say.
